Hey Robert,

Periodically, when CentOS releases a new kernel, we’ll have to do an updated 
kernel release with web100 support which may take a few days to get in place. 
If, during that time, you reboot (or install initially), it’ll come up in a 
non-web100 kernel. Since kernel updates won’t automagically reboot on 
install, it’ll keep running the older version even after an update. We send 
out announcements when we’ve released a new web100 version of the kernel. 
After those updates get installed, you’ll need to reboot to start using it.

Cheers,
Aaron
